Question

Please help find the percent of increase?!

Answer 1

you can solve this with proportion - first way

1.25 $/gal - 100%

1.75 $/gal - x%

1.25 : 1.75 = 100 : x => 1.25x = 1.75 * 100 => 1.25x = 175 => x= 175/1.25 =>

x= 140% => Increase is 40%

The second way, which is easier

1.25 *x = 1.75 => x= 1.75/1.25 = 1.4

Integer 1 mean 100% and 0.4 mean 40%

We can conclude that increase is 40%

Good luck!!!
